Application lcd November 6, 1225406. Serialll'o. 342,250.

The object of the invention is to provide a hydro-carbon. burner .ol"- the steam injectortype said burner having a steam spraying means.

The burner consists primarily ot a casing to which 1s connected an oil supply pipe, said casing is provided with 'a `nozzle Which in provided with a reciprocating needle valve..

yturn is provided with a steam spraying means.,

A reducer is detachably or removably located Within the casing. A. valve cylinder is lac ljustably located Within the casing and is The said adjustable valve casing and reducer coperate with cach other to control the suction powerolz the volume of steam passing through the casing. -ly such suction power the liquid'uel is drawn into the casing and mixes with the steam and the resultant mix- -jture is slprayed from the end'of the nozzle. 4Externa means is provided for adjusting the valve" cylinder longitudinally Within the casing.y The said casing is provided Witha steam inlet which islocated behind the oil inlet and the said valve cylinder is provided with' a steam admission ort.

ln'the accompanying ra\ving:-the figure is a-vertical sectional-view of the burner.A

The burner comprises the casing 1 to which is connected the steam 3. The said oil pipe the casing 1 in advance ipe 2 and the oil pipe eing connected with of the said steam pipe. The casing is provided With the mils' ture" outlet-4 to which is connected the discharge nozzle 5. The casing is also provided with the valve cylinder receiving portion 6. The reducer 7 is screw threaded in the dis charge 4y and is provided with a'n oil admis-` sion port'S. The said reducer 71's perforated longitudinally and is provided'with nular concaved surface 9 and the cylindrical portion 9 which extends over the oil pipe 3 and abuts at its end against the partition 1 provided in the interior of the casing 1. The oort 8 is located in the cylindrical portion 9.

the an-.

The valve 'cylinder l() is screw threaded in the receiving portion 6 of thecasing 1 and passes through the iartition- 1 and fits snugly Within the cylindrical portion -9 oi the reducer 7. Said cylinder 10 is adapted to move' longitudinally in said cylindrical portion of the reducer 7 and increase ordiminish the open area 'of' the port 8. Th

inder 10 an stuffing hox lllsurrounds the cy slides with relationv to the-'portion 6. The square or octagonal nut 12 is ixedto the cylinder 10. at a point beyond the'end oi the portion 6 of the casing 1. The stem 13 of `the needle valve' 1d passes longitudinally through the valve cylinder'l() an the latter is provided' Withza thread ltvhich engages the corres ending internal thread inthe portion 6 an affords means for moving the said stem longitudinally.l l f The stuling'box 16 surrounds the valve stem 13 and is arran ed to slide longitudinally of the valve cyinder 10. i'lhe outer end oi the stem 13 is provided with the turny ing knob 17. The needle'valve 1li is adapted to engage or seat upon the lsur-tace of thereduoe'd end 18 of the valve casing l0. The said reduced end 18 of the valve 'casing 1G is located Within the reducer 7 and the needle point of the valve 14 projects into the most contracted portion of the reducer 7. The valve casing 1G is provided vvith the steam admission port 19 which in alinement With the steam admission pipe 2. The nozzle 5 is provided with a discharge outlet 20 and the steam passa e2l which has' an outlet directlyunder the 'scharge outlet 20 and disposed in the same direction'. The steam pipe'ZZ is clonnected with the steam passage 2l.- V f The operation ofthe burner 'is as follows Theneedle valve le is closed against its seat. Steam is admitted throughthe pipe 2. into the casin 1 from whence it asses'to the port 19 into tlie cylinder 10. f4 The needlevalve 14 is then moved slightlyromits seat andthe steam ,escapesv frni the cylinder 10 andy passes into the reducer 7 vfrom Whichpoint lit' passes through'` the discharge @nozzle 5 and discharge outlet 20. lln rushing bythe oil admission port 8 suction is created which dravvslft'he liquid. fuel, up through the pipe 3.

is located below or aoA The valvev 23 having previously been opened,

the oil passes through' the admission port 8 'and mingles With thev steam and Vis thor'- Thismixture is expelled through,the discharge outlet 20 of `the vnozzle 5 where it is ignited. When it is' .pipe 22 and passage 21 and thus the mixture 1s 'sprayed as it comes from the discharge out'- let 20 of the nozzle 5. lThe needle valve 14 may be opened to such a degree as to regulate the volume ofsteam injected to anicety. The greater the volume of steam the greater will be the suction produced and the volume of oil will correspond. Should itbe desired to increase or decrease the quantity of the mixture the reducer 7 may be removed and one of a different capacity substituted in its stead. Then by turning the valve cylinder 10 the said cylinder will be moved longitudinally back or forthaccording to the direction in which it is turned vin order that the space between its inner end and the most contracted portion of the reducer may be regulated to a nicety. Thus, the space within which the mixing of the two elements takes place maybe increased or diminished at will to meet any requirement. l

'yf' Having described my invention what I claim as new and desire to secure by Letters- Patent 1s In an o1l burner, a casing having an o1'l 1nk'essere let, and steam inlet separated by a artition,

-a reducer located in the casing, an having a cylindrical portion extending over the oil 1nlet, and abutting against the partition of the casing, and provided with an oil inlet port; a valve cylinder projecting into the casing, with its forward end fitting snugly into the cylindrical portion of the reducer, and adjustable therein, to enlarge, or diminishthe opening of the oil inlet port of the reducer, said valve cylinder having a steam inlet port; and an adjustable valve controlling the discharge of steam from said valve cylinder into the ture in the presence of two witnesses.
